Explanation by: Admin

Frogs have multiple respiratory surfaces and can breathe through more than one organ depending on their life stage and environment:

  1. Lungs – Used for breathing on land.
  2. Skin (Cutaneous Respiration) – Frogs can absorb oxygen directly through their moist skin, especially when underwater.
  3. Buccal Cavity (Buccopharyngeal Respiration) – They can also exchange gases through the lining of their mouth.

This adaptation helps them survive in both aquatic and terrestrial environments.

Why not the others?

  • (A) Pleura – It is a membrane around human lungs, not an animal.
  • (B) Human – Humans rely only on lungs for respiration.
  • (C) Fish – Fish use gills exclusively for breathing underwater.
